IEC 60691:2023+AMD1:2024 CSV适用于通常用于室内的电器、电子设备及其零部件中的热链路，以保护它们在异常条件下免受过高温度的影响。 注1？该设备不是为产生热量而设计的。 注2？防止过高温度的保护的有效性逻辑上取决于热链路的安装位置和方法，以及热链路所承载的电流。 本文件可适用于在室内以外的条件下使用的热连杆，前提是此类热连杆周围的气候和其他环境与本标准中的条件相当。本文件可能适用于热-最简单形式的连接件（例如熔化条或线），条件是在运行过程中排出的熔融材料不会对设备的安全使用产生不利影响，特别是在手持或便携式设备的情况下，无论其位置如何。

IEC 60691:2023+AMD1:2024 CSV is applicable to thermal-links intended for incorporation in electrical appliances, electronic equipment and component parts thereof, normally intended for use indoors, in order to protect them against excessive temperatures under abnormal conditions.
NOTE 1？The equipment is not designed to generate heat.
NOTE 2？The effectiveness of the protection against excessive temperatures logically depends upon the position and method of mounting of the thermal-link, as well as upon the current which it is carrying.
This document may be applicable to thermal-links for use under conditions other than indoors, provided that the climatic and other circumstances in the immediate surroundings of such thermal-links are comparable with those in this standard. This document may be applicable to thermal-links in their simplest forms (e.g. melting strips or wires), provided that molten materials expelled during function cannot adversely interfere with the safe use of the equipment, especially in the case of hand-held or portable equipment, irrespective of its position.
